Replication seems to be failing due to the following exception:

/var/log/dataone/replicate/cn-replication.log

[ERROR] 2015-07-28 16:26:19,699 (ReplicationService:setReplicationStatus:219) Error in calling setReplicationStatus() for identifier autogen.2015051410063088508, target node urn:node:mnDemo6 and status of REQUESTED: Couldn't resolve the multipart request: null

The problem comes from CNResourceHandler.setReplicationStatus(pid) on the second of these lines:

Map files = collectMultipartFiles();

failure = ExceptionHandler.deserializeXml(new FileInputStream(files.get("failure")),
"Replication failed for an unknown reason.");

Turning on DEBUG logging shows the first line runs successfully:

metacat 20150728-22:28:31: [DEBUG]: done iterating the request... [edu.ucsb.nceas.metacat.restservice.D1ResourceHandler]

This could be the culprit: collectMultipartFiles() doesn't seem to add an entry to the return map with a "failure" key,
which probably yields a NPE in the FileInputStream constructor.
